Notes

Whenever a player's butt is defeated, the butt's owner will receive a notification telling them that "<Player> has kicked your butt."

Conversely, if you lose to the butt, the owner get a message saying "Your butt has kicked <Player>'s"

Unlike other monsters that scale to player stats, this one scales everything to Muscle. Instead of scaling Attack/stats to Moxie, they scale to muscle. Also of note is that they scale to un-buffed muscle, rather than buffed.

A player's butt will always lose initiative. I guess it isn't the most alert part of a player's anatomy.
